Come on in, the water's fine: Pick your favorite picture

A contest sponsored by the University of Miami's Rosenstiel School of Marine and Atmospheric Science has been recognizing the top underwater pictures taken by amateur photographers since 2005, but this year is different: For the first time, Internet users are being asked to select a "fan favorite" from five nominees. The voting runs through Sunday, and the People's Choice will be revealed along with other winners on April 18. Which is your favorite?

The arrangement of the pictures reflects the current standings in the "People's Choice" poll. Those rankings could change as the week goes on. For now, the identity of the photographers is being held back, although at least one of the nominees is making a personal plea on the University of Miami website. That's where you can register your vote — or "votes," since you can click for your favorite once a day through Sunday. Stay tuned for the big reveal on April 18.
